The solutions which result from the hydrolysis reaction yield characteristic reactions of aldehydes, such as reduction of hypoiodite, formation of oximes and dinitrophenylhydrazones.

The aldehydes in the hydrolyzed solutions are characterized either bytheir' reaction with dinitrophenylhydrazine to produce a dinitrophenylhydrazone or by hypoiodite determination.

In the first case there is employed an excess of solution of 0.2 percent 2,4-dinitrophenylhydrazine 'in 2N I-IC 1, and after a period of standing the dinitrophenylhydrazones that are formed are separated by filtration. They are then washed with 2 N HCl, dried and analysed.

In the second case the procedure followed is that embodied in the method adopted by Robinson and Mc- Leod, which is described in Loiseleurs book, Laboratory Technique, page 1344 (Masson Edition).

The aminated 'y-dialdehydes of formula (I) are only stable in strongly acid solution, with the primary amino compounds being-less stable than the secondary and tertiary compounds.

It is to be noted that the 2,5-dialkoxy tetrahydrofurans and their derivatives represented by formulae III and IV present cis-trans isomerism at the level of the alkoxy groups in positions 2 and 5. The substituents in 4-hydroxy)-3-tetrahydrofuryl and [3-N-[(2,5*dialkoxy 4-hydroxy')-B-tetrahydrofuryl]-aminoethyl and wherein R represents hydrogen or the immediately above meanings indicated for R1. In these new tetrahydrofurans, the alkyl moiety in hydroxyalkyl and alkaryl radicals preferably is cyclohexyl, while the preferred aryl substituent is phenyl, the preferred hydroxyalkyl substituent is hydroxyethyl and the preferred alkaryl substitutent is benzyl.

2,5-dialkoxy 3-amino 4-hydroxy tetrahydrofurans especially 2,5-dimethoxy 3-amino 4-hydroxy tetrahydrofurans, and the N-substituted derivatives thereof having formula (III), quaternary ammonium salts having formula (IV), tetraalkyl acetals having formula aminated and quaternary ammonium salts of tetraalkyl acetals having formula (VI) are valuable intermediate products which by way of acid hydrolysis allow to obtain useful solutions for the preparation of cosmetic compositions, particularly for the coloring of the skin and the strengthening or the restructuring of the hair.

The salts of the 2,5-dialkoxy 3-ammonio 4-hydroxy tetrahydrofurans of formula (IV) are also new compounds.

Moreover, the amminated 'y-dialdehydes of formula (I) and their quaternary ammonium salts havingformula (II) are also new compounds.

Additionally, the cosmetic composition can also include such conventional adjuvants as perfumes, thickening agents or dispersing agents. The active 'y-dialdehyde component, as set forth in l (6) immediately above, is generally present in amounts of about 0.5 percent to 12 percent percent by weight of the skin coloring or tanning compositions.

The aminated y-dialdehydes of the present invention effect a strengthening, restructuring or regeneration of the hair, with an improvement'of its cosmetic quality.

- operation.

This restructuring or strengthening of the hair is evidenced by a better appearance and an improved feel, softness and liveliness of the hair and general improvement of its cosmetic quality.

Usually this treatment to strengthen or restructure the hair is effected by applying to the hair a cosmetic composition containing at least one aminated y-dialdehyde of formula (1) and/or a quaternary ammonium salt of formula (2), the pH of the solution being between 1.5 and 9, preferably between 2 and 5 and permitting said composition to remain in contact with the hair for a period of about 5 60 minutes at a temperature generally between about and 50 C. The hair is then rinsed and if desired rolled on curlers and dried.

Thus the present invention also relates to a cosmetic composition for strengthening or restructuring the hair, said composition comprising an aqueous or aqueous alcoholic solution of about to 70 weight percent of an alkanol such as ethanol or isopropanol of at least one aminated y-dialdehyde of formula (1) and/or a quaternary ammonium salt of formula (2), the pH of the solution being between 1.5 and 9, preferably between 2 and 5. The 'y-dialdehyde or its quaternary ammonium salt is generally present in amounts of about 2 to and preferably 3 to 18 percent by weight of said composition.

Such a composition can include other cosmetic ingredients and be in the form of a solution, a creme or a gel. It also can be stored under pressure in aerosol containers together with an aerosol propellant such as dichlorodifluoromethane, trichloromonofluoromethane, their mixtures as well as other conventional aerosol propellants.

In order to better illustrate the invention, the follow- 1 ing examples of the preparation of the compounds of this invention and their use are given below.

Insofar as the melting. and boiling points are concerned, it is to be noted that, as indicated above, the

compounds of formulae (111) and (IV) presenticis-trans isomerism at the level of the methoxy groups in positions 2 and 5. The substituents in positions 3 and 4 can also increase the number of possible isomers. 1n the course of preparation of these compounds, no attempt was made to separate the isomers and for this reason the boiling points are often spread over a range of temperatures that is somewhat broad. Further the melting points are not particularly significant because they were determined on mixtures of isomers whose proportion may vary from one procedure to the next.

It is to be noted that the melting points above 50 C were determined on a Koffler bench: melting points below 50C were not determined.

The compound of Example 14 was imperfectly separated from the starting amine, the mixture containing 78 percent of the compound of Example 14 and 22 per cent of the starting amine. These percentages were determined by measurement of the nitrogen.
